When you can see what the request is, and what information it includes,
and when you can see how nginx-or-something-else can take that information
and determine the correct public and private addresses to use, then you
may have enough information to configure sub_filter (or something else)
to return the content that you want.

Most of those missing pieces are not nginx-specific.

There might be someone here who knows about them; but if they are
CoreOS-specific, you may have better luck on a CoreOS list.

Good luck with it,
